We can never obtain peace in the world if we neglect the inner world and don't make peace with ourselves. World peace must develop out of inner peace. Without inner peace it is impossible to achieve world peace, external peace. Weapons themselves do not act. They have not come out of the blue. Man has made them. But even given those weapons, those terrible weapons, they cannot act by themselves. As long as they are left alone in storage they cannot do any harm. A human being must use them. Someone must push the button. Satan, the evil powers, cannot push that button. Human beings must do it.
